David Drysdale 8898d2ec57 Secretkeeper: add AuthGraph key exchange ... Add `ISecretkeeper::getAuthGraphKe()` method to the Secretkeeper HAL. Align the AIDL targets between AuthGraph and Secretkeeper, and add some defaults that automatically link to the current version of the Secretkeeper AIDL targets. Move the non-secure implementation of AuthGraph to run the TA in a separate thread. Alter the nonsecure implementation of Secretkeeper so that it no longer directly implements Secretkeeper functionality, but instead re-uses common code from the Secretkeeper reference implementation. This involves re-using the common implementation of the HAL service (from `authgraph_hal`), but also involves using the reference implementation of the the TA code that would normally run in a separate secure environment. The latter code expects to run in a single-threaded environment, so run it in a single local thread. Note that the negotiated session keys emitted by AuthGraph are not yet used by Secretkeeper (coming in a subsequent CL). Extend the Secretkeeper VTS tests to invoke the AuthGraph VTS inner tests on the returned IAuthGraphKeyExchange instance, exercising the instance as an AuthGraph sink.
